摘　　要：为精确诊断三座店水库坝体左坝肩渗漏隐患,引入物探手段查明渗漏部位和库水位关系,综合地质勘察、示踪法、温度场法、单孔稀释流速法和孔内电视等现场渗漏探测情况,对探测数据进行相互校验,取得一致的分析结果。结果表明:现场试验的三条连线上均存在渗流通道,主要为绕坝渗漏;通过流速检测与孔内电视成果对比分析,精确定位每个断面的主要严重渗漏部位,为后续坝体制定合理的渗漏处理方案和保证工程质量提供依据。In order to accurately diagnose the seepage risks at the left abutment of the Sanzuodian Reservoir Dam,geophysical methods were introduced to identify the relationship between the seepage location and the reservoir water level.The study integrated geological surveys,tracer methods,temperature field methods,single-hole dilution flow velocity methods,and borehole television inspections.The field data was cross-verified to achieve consistent analytical results.The results showed that seepage channels were present along the three survey lines,mainly in the form of dam-bypassing seepage.By comparing flow velocity detection and borehole television results,the primary and most severe seepage locations in each section were accurately identified,providing the basis for developing a reasonable seepage treatment plan for the dam and ensuring engineering quality.
